2 Claims. (ci. 132-13) 'I'his invention relates to applicators and, more particularly, to an improved scalp medicator.

One object of the invention is to provide a scalp medcator by the use of which it will be possible to distribute liquid medicaments to the scalp for treating said scalp and improving the condition of the hair.

Another object of the invention is to provide a device of this character employing a handle which defines a reservoir for containing the medicament.

Another object of the invention is to provide a scalp medicator wherein improved valve means is employed for controlling ow of the liquid medicament from the reservoir.

Still another object of the invention is to provide, in a'device of the character mentioned,- valve means in the reservoir which will be-movable for preventing an air lock, with the result that free ow of the liquid medicament from the reservoir will be assured.

A still further object of the invention is to provide a scalp medicator having a comb formed with tines, said tines being hollow and having discharge openings formed in their side walls so that clogging will be prevented.

And still another object 'of the invention is to provide a scalp medicator which is simple in construction and which will be highly eflicient in use.

Other objects of the invention, not specifically mentioned hereinbefore, will become apparent during the course of the following description.

In the drawing forming a part of lmy application:

4Figure 1 is a side scalp medicator,

Figure 2 is a longitudinal sectional view of the device,

Figure 3 is an enlarged detail sectional view on the line 3-3 o1.' Figure 1,

elevation oi ,my improved Figure 4 is an enlarged detail sectional viewV showing the control valve,l

Figure 5'is a vertical sectional view on the line Figure 9 is an enlarged detail vertical sectional view showing the air valve in closed position,

Figure 10 is a detail transverse sectional view on the line IIJ-I0 ot Figure 8, an'd Figure 1l is a detail transverse sectional view on the line II-II of Figure 9.

Referring now more particularly tothe drawing, wherein like numerals of reference designate like parts throughout the views, the numeral I indicates in general the body of my improved scalp medcaton The'body I includes a handle 2 and a comb 3. The handle 2, as best seen in Figure 2, is enlarged and is formed with a hollow interior which defines a reservoir 4.

The body I is formed of metal, hard rubber, plastic, or other suitable material, the handle being, of course, of a shape to iit snugly in the hand of a user. Formed on the handle 2 medially of its length and/width is an upstanding boss 5 which is formed with a Iiat upper Wall 6. The boss 5 is apertured to dene an vvinlet 1 through which medicament may be passed to thev interior of the reservoir 4. Extending throughout the length of the inlet 'i and communicating therewith is an arcuate groove 8, the purpose of which will be set forth in more detail hereinafter. Screwed in the inlet 'I is a plug valve 9 which is formed with a knurled head I0 having a iiat under surface II which is engageable with the fiat upper surface 6 of the boss 5 for providing an air seal. Formed in the plug valve and extending throughout its length is an arcuate groove I2 which cooperates with the groove S for deiining an air passage I3. As seen in Figure 8, when the plug valve is unscrewed, for disposing the head I0 thereof above the at upper surface V6 of theboss 5, the grooves 8 and I2 may be alined for denning the air passage or vent i3. Air will flow between the boss and the head I0 and through the passage I3 to the interior of the reservoir for permitting free ow of liquid therefrom. The plug valve may be entirely removed when it is desired to add medicament to the reservoir. When the plug valve is screwed down to closed position, as shown in Figure 9, the under surface II of the head I0 will engage the upper surface of the boss 5 and provide a seal. As shown in Figure 11, when the head is in closed position, the grooves 8 and I2 will be out of alinement.

The comb 3 includes a head I4 which is formed with a channel I5 extending throughout its length. The channel I5 communicates with the interior of the reservoir 4 through a passage I6 between the Vhandle 2 and said comb 3. Formed on the head I4 are spaced tines or teeth I'I each of which is formed with a discharge passage I 8 which communicates with the channel I5. As will be observed, each of the passages I8 is smaller than the channel I5. Each of the tines or teeth II, as best seen in Figure 3, is formed with a discharge opening I9. The openings I9 are disposed at one side of the lower end portions of the teeth. 'I'he purpose of the location of the discharge openings I9 is to prevent clogging of the teeth which would otherwise occur.

Formed on the body I, between thecomb 3 and the-handle 2 is a boss 20 and screwed through the boss into the passage I6 is a control valve 2|, said valve being formed with a knurled head 22 and, near its lower end, with a discharge opening 23. As best seen in Figures 4 through 'I 'of the drawing, the opening 23 is disposed so that it may be caused to aline with the passage I6. More specifically, when the control valve is shifted to the position shown in Figures 4 and 6, the opening 23 will be in alinement with the passage `lli and liquid will be permittedfto flow into the channel I5 and' thus into the tines or teeth of the comb, for discharge from the openings I9. However, when the control valve is rotated substantially one-half turn, the opening 23 Will be disposed in the position ,shown in Figures 5 and 7. That is to say, the opening 23 will be disposed at a right angle to the passage I6 and liquid will be prevented from flowing into the channel I5.

It is believed that the operation of my invention will be clearly understood, after a reading of the foregoing. However, a brie:` statement is not believed to be out of place. The control valve 2| is rst closed and the plug valve is remove-d. Medica-ment is poured into the reservoir 4 and the plug Valve is again screwed into place. When it is desired to rnedicate the scalp, and thus improve the condition of the hair, the valve 2| is rotated to open position for permitting medicament to pass into the channel I5 and through the teeth I'I for discharge from the openings I9. In order to insure the free ow of medicament, air is admitted to the reservoir by unscrewing the plug valve and aligning the grooves 8 and |2, in the manner set forth hereinbefore.

Itis desired to emphasize that, inasmuch as the discharge openings I9 are disposed at one side of the teeth I1, said openings will not readily become clogged with dandrul or the like, and thus free ow of medicament will not be obstructed.

By the use of my improved scalp medicator, it will be possible to medicate the scalp in a simple and highly eflicient manner, with the result that the hair can be properly treated for keeping it in the best possible condition. My improved medicator is'light in weight and simple in construction. There are but few parts to the device so that the same maybe easily kept clean and otherwise in good condition.

Having thus described the invention, what is claimed as new is: 1. A device of the class described including a body having a reservoir and a boss formed with an inlet, said inlet having a groove and said boss having a at top wall, a plug valve screwed in the inlet and having a head vprovided with a flat under surface adapted to engage the flat upper surface of the boss and form a seal in closed position, said plug valve having a groove and being rotatable for unseating the head from the boss and alining the grooves to provide a vent for the interior of the reservoir.

2. In a fountain comb, a handle having an internal liquid reservoir and provided with a hollow interiorly threaded boss communicating with said reservoir, the interior threads on one side of the boss being cut away to `form a vertical air passage, and a combined closure plug and air 1 vent having a threaded shank detachably engaging the threads on the boss and provided at its upper end with an enlarged head adapted to normally seat on the adjacent end of the boss and close said air passage, the threads on one side of the shank being cut away to form a vertical groove adapted to register with the air passage when the plug is rotated to unseat the head thereof thereby to permit venting of the reservoir through said vertical air passage.
